has made it possible to display specimens belonging to the Spear 

 collection of Polynesian material and other specimens withheld 

 from exhibition because of lack of space. A further display of 

 California and Nevada basketry from the Gottschall collection has 

 also been possible, while the archaeological collections from Egypt 

 and Europe and ethnological material from India and the Philippines 

 have been rearranged. 



The department has as heretofore been under the care of Miss 

 H. N. Wardle, who, beside the rearrangement above described, has 

 prepared numerous labels. 



Mr. Clarence B. Moore has placed on exhibition the valuable 

 objects found on his Green River expedition and has provided a 

 new horizontal exhibition case for their display.

Report of the Curator of the William S. Vaux Collection. 



The past year has been rendered epochal in the history of the 

 William S. Vaux collection by the installation of new cases, in which 

 the entire collection has been rearranged. On completion of re- 

 labelling, which is under way, the collection will be in creditable 

 condition. 



Accessions during the year include ten specimens of calcite and 

 geyserite from Yellowstone National Park, presented by Mrs. 

 Walcott, and eighteen specimens purchased. Most important 

 among the latter were hopeite and parahopeite from Rhodesia and 

 several meteorites. 



I again take pleasure in acknowledging the active and efficient 

 assistance of Mr. Samuel G. Gordon, on whom devolved most of 

 the actual work of transferring the collection. 



Respectfully submitted, 



F. J. Keeley, Curator Wm. S. Vaux Collection.
